FortiOS 5.4: Redundant Interfaces in Firewalls

By May 10, 2016No Comments

While we’d love for everyone to have completely redundant firewall setups, that isn’t always a viable possibility. That’s why FortiGates now have an excellent feature in FortiOS 5.4, redundant interfaces. This feature enables interface redundancy at a network level, and is great¬†mainly for growing small and medium businesses that already have redundant network core infrastructures but not more than one¬†firewall. If you’ve upgraded your FortiGate to FortiOS 5.4, the below steps will walk you through enabling it.

Remember, though, this won’t protect you from a full unit failure!

Under Network on the left-hand side, select Interfaces.

Select the Create New dropdown and then choose Interfaces:

From here, choose Redundant Interface under the Type dropdown:

Select the plus sign next to Physical Interface Members to choose from available ports:

From there, name your new interface, select which you would like to use as the redundant link, set the IP and any admin access. Overall, a pretty simple process to achieve a little more redundancy if you don’t have a redundant firewall but you do have core networking redundancy.

If you have questions about your FortiGate or getting one, don’t hesitate to email us or give us a call at 502-240-0404!
